Polarization-Sensitive Third Harmonic Generation in resonant silicon nitride Metasurfaces for deep-UV Emission
Shroddha Mukhopadhyay, Maria Antonietta Vincenti, Radu Malureanu +3
We present a combined experimental and theoretical study of enhanced third-harmonic generation (THG) in silicon nitride metasurfaces. These structures exhibit strong resonant nonli…
Gold-polymer hybrid metasurface for polarization-independent enhanced third harmonic generation in the ultraviolet
Shroddha Mukhopadhyay, Ana Conde-Rubio, Jose Trull +4
We present a combined experimental and theoretical study of nonlinear light-matter interactions in a three-dimensional gold-polymer hybrid metasurface. In contrast to conventional…
High-harmonic generation from subwavelength silicon films
K. Hallman, S. Stengel, W. Jaffray +10
Recent years have witnessed significant developments in the study of nonlinear properties of various optical materials at the nanoscale. However, in most cases experimental results…
Below the Surface: Unraveling the Intricacies of the Nonlinear Optical Properties of Aluminum through Bound Electrons
M. Scalora, K. Hallman, S. Mukhopadhyay +8
By uncovering novel aspects of second harmonic generation in aluminum we show that there are unusual and remarkable consequences of resonant absorption, namely an unexpectedly crit…
